WINDING CHUCK FOR FABRIC, PAPER, AND OTHER MATERIALS,

Application filed November 8, 1921. Serial I To. 513,314.

'1 0 all whom it may concern Be it known that OTTERBEIN P. KiaAcorn, acitizen of the United States, residing at East Rutherford, in the countyof Bergen and State of New Jersey, has invented certain new and usefulImprovements in Winding Chucks for Fabric, Paper, and Other Materials,or' which the following is a specification.

This invention has relation to certain new and uset'ul improvements in awinding chuck for fabric, paper and other materials and has for itsprimary object the provision of a device of this character which will beof extremely simple construction and operation as well as highlyeflicient in use and by means of which the material may be readily woundinto cylindrical. form without waste of any of the material and withoutthe necessity of I first providing finished tubes upon which to wind thematerial.

The invention has for another object the provision of a device of thecharacter set forth which will be of such construction and operationthat the material may be gripped and held along one edge until thematerial is wound upon the shell or mandrel and then instantly releasedto permit withdrawal of the winding device from the wound material, orwithdrawal of material from device as occasion may require.

The invention has for another object the provision of a device of thecharacter set forth which will serve to securely hold the ends of thematerial while being wound into the desired form and size, and theninstantly released and the devicewithdrawn from the wound material ormaterials withdrawn from the device without damage to the material.

The invention has for a further-object the provision of a device of thecharacter stated which will be composed of the minimum number of parts,may be readily assembled or dissembled, as desired and serve to hold thevarious materials together with any second material which it may bedesired to wind into or wind with the first material, the gripping dogbeing of such construction that it will serve to hold one or morematerials in proper position during the winding operation but willpermit the material or materials to be readily released when it isdesired to withdraw the winding device or the material, as desired.

lVith the foregoing and other objects in view as will appear as thedescription pro-' ceeds, the invention consists in the novelconstruction, combination and arrangement of cooperatingelements ashereinafter more specifically set forth, claimed and shown in i lookingin the direction indicated by the arrows.

Referringmore in detail tothe drawings in which similar referencecharacters, designate corresponding parts throughout the several views,1 indicates the driving spindle which may be provided in its rear endportion with a central bore or other socket 2,

for the reception of a supporting device or driving shaft, not shown.This socket may be smooth, as indicated by dotted lines in Fig. 2 orthreaded, as desired. Thedriving spindle 2.has its central portion 3-reduced and the windingshell or mandrel 41: mounted I thereon, asuitable spacing washer 5 being positioned at the end of the shell ormandrel 4L and between the inner end of said shell or mandrel 4L and thelarger or rear end portion. of the driving spindle l, as shown clearlyin Figs. 1 and 2 of the drawings.

The winding shell or mandrel l has its outer end portion hollow to formthe socket 6 within which the gripping dog 7 is positioned. One side ofthe socket end or outer end portion of the winding shell or mandrel l isopen, as shown clearly in Figs. 2, 3 and 4, to 01513 the materialreceiving slot 8 having one curved or convexed sidewall 9 and a straightopposite side wall 10. The nose 11 of the gripping dog 7 extends intoand is adapted to work in the slot 8, as shown clearly in Figs. 3 and4-. This dog 7 has a curved or convexed wall 12 for one side of the nose11 thereof while the opposite side of the nose 11 is straight tocorrespond with the straight wall 10, as clearly shown at 13 in Figs. 3and 4;. The curved or converted side wall 12 of the nose 11 ispositioned opposite and adapted to co-operate with the curved orconvened wall 9 of the slot 8 in holding the edge of the materialinserted in said slot- 8, as will be later clearly understood. Byreferring to Fig. 2 of the drawings, it will be clearly seen that thegripping dog 7 is mounted on the reduced forward end portion 14 of thedriving spindle 3. The gripping dog 7 is keyed for rotation with thedriving spindle 3 by means of the key 15 at the outer end por tion ofthe driving spindle 3 and the gripping dog 7, as shown in Figs. 2, 3 and4. A washer 16 is extended over the outer end of the driving spindle 3and is of sufiicient diameter to cover the end of the locking key 15 andprevent the latter from working out of position. A stop screw 17 is eX-tended through the washer 16 and threaded into the outer extremity ofthe driving spindle 3, as shown clearly in Fig. 2 of the drawings. Thiswill serve to prevent the washer 6 from moving out of position andreleasing the locking key 15 for the grip 'iing dog 7.

It is believed that the complete construction and operation of thewinding chuck may now be readily understood without further detaileddescription. It may be stated, however, that when this device is to beemployed for winding material or materials thereon, the end or a portionof the end of the material or materials should be inserted in the slot 8between the faces 12 of the gripping dog nose 11 and the face '9 o f theslot 8. The entire winding chuck should then be rotated in the properdirection so as to drive this face 12 of the gripping dog 11 toward thewall 9 to grip the material between said walls and hold the material ormaterials in position while being wound upon the shell or mandrel 4.

hen the winding operation is completed, the first end of the material ormaterials may be readily released by turning the winding spindle 3 inthe direction to move the nose ll of the gripping dog 7 away from theend of the material and release the same, after which the entire windingchuck may be withdrawn from the roll of material, or the materialwithdrawn from the winding chuck. It is also understood that it is notnecessary to grip the entire end of the material or materials to bewound into cylindrical form but a winding operation may be just aseffective it only a portion of the end ofthe material or materials areheld by the gripping dog 7, in the manner stated. It is also evidentthat the shape of the shell or mandrel i may be carried as desired.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes in the details ofconstruction and arrangement oi parts may be resorted to within thescope of what is claimed without departing from the spirit of theinvention.

What I claim is A winding chuck comprising a driving spindle, a shellmounted on a reduced portion of said spindle and having an eXtendedsocket portion with the opening forming a material receiving slot, and agripping dog secured upon said driving spindle within said socket andhaving a nose extended into said material receiving slot with wallscorresponding with the walls of said slot and adapted for cooperationtherewith in gripping at times an end portion of a material extendedinto said slot.

In testimony whereof I aiiix my signature.
